[0023] As an embodiment of the present invention, the chute 41 is provided with an air bag 43; the splint 52 is equipped with a fixed block 522 through a spring on the side walls close to each other, and the side wall of the fixed block 522 is provided with a No. 1 rubber tube 523 communicates with the air bag 43; through the cooperation of the air bag 43, the fixed block 522 and the splint 52, the fixing effect on the model is strengthened; during work, when the teacher needs to use the device to assist teaching, the model is first assembled and then placed on the top plate 4, to be After the position of the model is stable, the screw 51 is rotated by the handle 511. After the screw 51 rotates, the nut 521 drives the splint 52 to slide towards each other, thereby realizing the closeness between the splints 52. During the rotation process of the screw 51 Among them, the lead screw 51 squeezes the air bag 43, and the air bag 43 transmits its internal gas to the No. 1 rubber tube...
